Years ago, my husband bought me a sapphire ring so we decided to visit it again. Coster’s is family-owned that has been in business since the 1800’s. During the tour, we saw craftsmen working on polishing diamonds, the crown Queen Victoria had made for her that she rejected because the diamond was not bright enough, and photos of famous kings, queens, and others who have purchased from Costner. I looked at a ring with a one caret diamond that was available for purchase for a mere $44K plus. There are a number of stairs in the home so the tour is not for those with mobility issues. The tour is free and lasts approximately 20 minutes.
